TECHNICAL FIELD

This application relates to a device that assists a toddler in learning to walk, and in particular to such a device having an interactive display device, wherein multiple adjustment modes are provided for increased suitability to the particular stage of development in which the toddler is learning to walk.

BACKGROUND OF THE INVENTION

Devices exist which assist toddlers (e.g., 1-2 year olds) in learning to walk. These devices, referred to herein as toddler walkers, may exist in different forms, but in general include a body and four wheels, and a handle suitable for the toddler to hold onto while he or she begins to walk. The walker provides a stable vehicle that the toddler can lean on as they take their first steps, eventually enabling the toddler to gain the balance, strength, and confidence to walk on their own without relying on the walker.

These existing walkers do not, however, account for differences in size, strength, or dexterity of the toddler, or where they may be on the developmental curve with respect to learning to walk unassisted. For example, a toddler who is just starting to learn to walk has different needs than one who is close to walking unassisted. The prior art walkers may either be too difficult for a beginning walker, and/or too easy for a more experienced walker. Additionally, these walkers lack the ability to provide engagement of the toddler with the walker through, e.g., an interactive display device or the like.

SUMMARY OF THE INVENTION
